Anoxia Complications In Sickle Cell Persons

Anoxia in sickle cell disease patients occurs when the body or brain completely loses or is cut off from its oxygen supply. Anoxia is resultant of hypoxia. 

When the patient’s body is damaged or injured by a lack of oxygen, it is called hypoxic-anoxic injury or damage. Hypoxia can be a result of many conditions, such as; low oxygen at high altitudes, significant blood loss, carbon monoxide, and other poisonings, breathing difficulties that lower oxygen supply such as asthma or pneumonia, low blood flow to organs such as from a stroke, or heart problem, sudden injuries that affect breathing, such as near-drowning or choking.

When hypoxia then develops into anoxia, the parts of the body that need oxygen to function can stop working properly, it includes; the brain, the heart, the kidneys, and bodily tissues. In about four to five minutes of oxygen starvation in the brain, it causes permanent brain damage, this is because, the brain cells can die from lack of oxygen, and they slowly die from an inadequate supply of oxygen to the brain.

Anoxia has symptoms that are not noticeable at first instance and so in this case it takes several days or a few weeks before symptoms start to appear.

The symptoms are; sudden and frequent mood or personality change, memory loss, slurred speech or forgotten words, change in already said judgment, difficulty in walking or moving the arms or legs normally, weakness, feeling dizzy recurrently, disorientation, unusual and severe headaches, seizures, hallucinations, loss of consciousness that occurs suddenly and repeatedly, and trouble in concentrating. There are several types and causes of anoxia, and each type has a different internal and external cause.

The internal cause is lack of oxygen to the brain or heart vessels, external cause could be less available oxygen or inhaling environmental toxins. The types are anemic anoxia, toxic anoxia, stagnant anoxia, and anoxic anoxia
